Which type of piping is exempt from release detection if installed or replaced after a certain date?

Safe-Suction Piping
Double-Walled Piping
Single-Walled Piping
Overfill Prevention Piping

The correct answer is: Safe-Suction Piping

Safe-suction piping is exempt from release detection requirements when it is properly designed and installed as part of a storage tank system. This type of piping is configured to prevent the release of regulated substances to the environment, as it relies on suction to draw product from the tank without the risk of leaks. Specifically, safe-suction piping is designed to be capable of containing any potential leaks due to its operational characteristics, which include being located above the water table and able to ensure that any liquid that escapes will be siphoned back into the tank. This exemption is based on the understanding that when safe-suction systems are correctly installed and maintained, the risk of release to the environment is minimized, thereby allowing them to bypass the otherwise required release detection measures. The other types of piping noted in the question may not provide the same level of leak prevention or operational safety, thus requiring different levels of monitoring and release detection to ensure environmental protection.
